Dec. 6, 1932. J. F. DAWSON CAHBONATiNG DEVICE Filed April 16, 1951 Patented Dec. 6, 1932 UNITED STATES PATENT OFFICE JAMES F. DAWSON, OF GALVE'ION, TEXAS, ASSIGNOR TO TRIPLE XXX COMPANY A CORPORATION OF TEXAS cnnnonnrme DEVICE Application filed April 16,

This invention relates to improvements in carbonating devices and pertains particularly to a combined carbonator and mixing valve.

The primary object of the present invention is to provide a carbonating device which automatically operates, as the pressure is reduced at an outlet, to open a valve forthe introduction of gas thereinto as the water is admitted, the entrance of water to the mixing device actuating the valve controlling the admission of gas.

Another object of the invention is to provide a carbonator device having a water valve and a gas valve with a connection-between the two valves whereby the gas valve is actuated by and upon the movement of the water valve, the water valve being in turn actuated by the pressure of water thereagainst. 1

Still another object of the invention is to provide a carbonator in which an improved means is employed for agitating the gas and water to obtain the thorough commingling thereof and'solution of the gas in the water.

A still further object of the invention is to provide an improved water and gas mixer and valve structure for a carbonator in which the valve structure is of relatively simple but rugged design so that the failure of any part thereof is unlikely to occur.

The invention will be best understood from a consideration of the following detailed description taken in'connection with the accompanying drawing forming part of this specie fication, with the understanding, however, that the invention is not confined to any strict conformity with the showing of the drawing but may be changed or modified so long as such changes or modifications mark no material departure from the salient features of the invention as expressed in the appended claims.

' In the drawing:

Figure 1 is a view in longitudinal section through the carbonator structure embodying the present invention.

Figure 2 is a view in top plan of'one of the bafile or agitating cones.

Figure 3 is a view intop plan of another 1981. Serial No. 530,706.

of the baflie or agitating cones, portions thereof being broken away.

Figure 4 is a detailed sectional view taken on the line 4-4 of Figure 2. Figure 5 is a fragmentary view of the cone shown in Figure 3 looking in the general direction of the arrow. 7 Referring now more particularly to the drawing, wherein like numerals of reference indicate corresponding parts throughout the several views, the numeral 1 indicates the main body portion of the valve portion of the carbonator device.

This, as shown, is a cylindrical body which is exteriorly threaded at its upper end for connection therewith of the coupling 2 which joins the valve body 1 with the cylinder 3. The lower end of the body 1 is interiorly threaded, as indicated at 4, and this has ex tended thereinto the reduced portion 5 of a casting 6. The casting 6 has a passage openplug is down in the passage 7 the flutes will be covered, but when it is raised they will extend beyond the upper end of the portion 5 of the casting and permit fluid to pass into the body 1'.

Intermediate its ends the body 1 has an angularly directed, exteriorly threaded, nipple 11 into which is extended a needle valve car rier 12, the outer end of which is flanged, as at 13, to limit its inward movement. This carrier 13 is secured in position by the collar 14 which surrounds the nipple and forces the flange 13 inwardly against the end of the nipple. A suitable packing or gasket 15 is interposed betweenthe flange 13 and the end of the nipple, as illustrated, and there is'also a gasket interposed between the lower end of the body 1 and the shoulder portion of the casting 6 which abuts thereagains't, as indicated at 16.

The carrier 12 has a longitudinally extending passage therethrough which, at its inner end, is relatively narrow, as indicated at 17, While intermediate its ends it is slightly enlarged, as indicated at 18, and at its outer end it is still larger, forming the chamber 19. The wall of the chamber 19 .is interiorly threaded to receive the threaded reduced end 20 of the gas inlet nipple 21, the outer end ofwhich is reduced slightly and threaded, as indicated at 22, to facilitate the coupling of a gas pipe thereto. The inner end of the passage through the nipple 21 is reduced, as indicated at 23.

Extending through the inner end portion 17 of the passage through the valve carrier 12 is the stem of a needle valve, which is indicated generally by the numeral 24. The point of this valve enters the reduced end of the passage 23 and intermediate its ends this stem is enlarged to fit snugly in the portion 18 of the passage through the carrier. A spring 25 located in the portion 18 of the valve carrier normally projects the needle valve to seated position in the passage 23. The inner end of the needle valve stem is engaged by a finger 26 which forms a part of anactuating lever 27. This actuating lever 27 is pivotally mounted, as at 28, upon the inner end of the body 12 and it extends downwardly and is curved adjacent its free end for contact with the top of the reciprocable valve plu 8. A gas through t e body 12 rom the chamber 19 into which the gas is allowed to escape by the needle valve to the interior of the body 1 the inner end of this passage being covered by a finely apertured body 30 which tends tothor oughly disperse the gas in the water with which the body 1 is filled.

Within the cylinder 3 there are located a series of frusto-conical bodies of alternately large and small diameter, the larger bodies being indicated by the numerals 31 while the smaller bodies are indicated by the numerals 32. These alternately large and small bodies are separated by spacing members 33 and are held in unitary relation by a rod 34, the upper end of which has a head against which the upper cone body presses, while upon the lower end is a nut 35 which retains the members in place thereon.

The larger bodies 31 have straight lower edge flange portions 36 which are of an exterior diameter to snugly fit in the cylinder 3 and the flat tops 37 thereof are each providedwith a circular series of outlet ports 38 which are arranged to all discharge in the same direction. The smaller bodies 32 are each provided with a straight lowered portion 39 which rests upon the sloping top of a larger body disposed therebeneath. The h assage 29 is formed straight bottom flange portions of the smaller cone bodies 32 are provided with a series of vertical covered outlet ports 40 all of which are arranged to discharge in the same direction and their direction of discharge is opposite to the direction of discharge of the ports 38 of the. larger bodies.

The upper end of the cylinder 3 has a suitable reducing coupling 41 connected there with with which is connected a coupling 42 to which may in turn be attached a lead-01f pipe (not shown).

From the foregoing description it will be seen that when the pressure is reduced within the cylinder 3 or the valve body 1, the pressure of water entering the passage-7 will cause the valve plug 8 to lift until the flutes 6 are uncovered so that the water may flow into' the body of the carbonator.

This lifting of theplug 8 will cause the actuation of the lever 27 and consequently the opening of the needle valve 24 thus permitting gas to enter through the nipple 21 and the passage 29 to mix with the water in the valve body. As the mixed gas and water flows upwardly through the cylinder 3 it will be violently whirled back and forth as it passes through the ports 38 and 40 of the alternate large and small bodies 31 and 32, so that the complete mixing of gas with the water will be obtained.
